Combines the Nauticam NA-A7RIII Housing with both Macro and Wide Angle lens ports, extensions and gears to fit the Sony 16-35 GM and 90 macro lenses. Fits both the Sony A7RIII and new A7III camera bodies. Included also is a great lighting system consisting of 2 Sea & Sea YS-D2J strobes, mini flash trigger, fiber optic sync cords and the Kraken Hydra 5000S+ lumen light.

Fits Both the Sony a7RIII and a7III Camera Bodies

The Sony a7R III is the company's latest high-resolution full-frame mirrorless camera. Achieving an overall DxOMark sensor score of 100 points, the same as the Nikon D850, makes the a7R III the highest-scoring mirrorless system camera to date, beating out its predecessor, the a7R II.

The new Sony a7III body is the latest model of this popular camera. It features a full frame mirrorless 24.2 MP sensor that offers 14 bit RAW imaging at 10 fps. The sensor itself is 5-axis stabilized and features 693 phase-detection AF points covering 93% of the image area in addition to 425 contrast-detection points. The A7 III is able to capture UHD 4K at 30p and 100 Mbit/s and includes Hybrid Log Gamma as well as Sony S-Log.  

Nauticam NA-A7RIII for Sony's Alpha 7R III (A7RIII) & A7III cameras

A professional housing befitting of a top-of-the-line camera, the NA-A7RIII underwater housing provides fingertip access to all key camera controls in a rugged and reliable aluminum underwater housing. Ergonomic camera control access is one of the defining strengths of a Nauticam housing, and the NA-A7RIII continues this tradition. Essential camera parameter changes are made from the handles, without awkward reaches.

The NA-A7RIII housing inherits the core design elements from the Nauticam pro DSLR range, and bundles them in a more compact package. A patented port locking lever allows lens changes to be made in seconds. Opening the housing for quick battery and media changes is fast and easy with the locking housing latches. All aspects of the system are a seamless extension of the camera.  

Integrated Electronic Vacuum Check and Leak Detection System

The NA-A7RIII ships with Nauticam's new vacuum system with integrated electronic vacuum and leak detection monitoring system for extra piece of mind. Our A7RIII Ultimate System includes the necessary vacuum valve and hand pump.

Ports & Gears

The Optical Ocean Ultimate A7RIII system includes a locking extension ring, port and adapter with zoom gear for the Sony 90mm lens. This lens works especially well for close up and macro shots. We've also included a 180mm optical glass dome port with a zoom gear for the Sony FE 16-35mm F2.8 GM lens so you can take excellent wide angle photos.

Sea & Sea YS-D2J Strobes

The Sea & Sea YS-D2J represents the best in modern strobe technology. With a Guide Number of the 32 it is one of the most powerful strobes available while being half the size and weight of its competitors. It has a two power target light, and lighted back that shows its modes, with 13 steps of manual adjustment.

Kraken Hydra 5000S+ Lumen Wide, Red, Spot and UV Video Light

The Kraken Hydra 5000+ lumen light has 2 buttons for ease of use, a water resistant light head for flood protection, as well as spot, flood and red beams. It features a COB LED for the best, and most uniform, flood beams for your photography and video needs. This is a newly updated version of the popular Hydra 5000, the only difference is a new LED which provides a CRI of 90, compared to 82 on the original version. This gives a better 5000K accuracy.

This 5000S+ Video Light also comes with the added feature of having a Spot and UV light along with the Wide and Red light. So it can be used as a regular dive light, or as a focus or video light as well. Divers who want to shoot fluorescent photography will have a strong light source. The two button layout mean that you use one button to select the mode, and the other to select the output level. No hard-to-remember sequences on a single button. All of the lights utilize multi-cell battery packs, with quality, fast chargers. Recharge time is about 2.5 hours from a completely drained state. Extra battery packs are available.

The Kraken Hydra lights come in a complete set that includes ball and YS style mounts, spare orings, charger and a carrying case.

I ended up with far more keepers than normal. I continue to be impressed with Nauticam housings and Sony cameras, and this was without a doubt the easiest and most rewarding photo week yet!
